Seed drills with combined coulters in No-till technology in soil and climate zone conditions of Kazakhstan

Kazakhstan is one of the top ten countries in the world that use careful farming with a total area of 2 million hectares, therefore, the priority area of scientific research in the field of agriculture is the development and improvement of effective means: seed drills, tillage machines and mechanisms. As part of the research, tests were conducted with the use of experimental seed drills with various combinations of coulters: (1) double-disc and chisel coulters installed in different rows, (2) double-disc coulters and cultivator sweeps with seed distributors for band sowing. The research showed a higher efficiency of the use of combined coulters in comparison with only sweep rows in seed drills both in terms of agrotechnical indicators (yield, stubble conservation, uniformity of seed depth and field fullness germination of seeds, drag force of the drill), and from the economic effect terms. The results of this research can be used in the agricultural sector, regardless of the country and region, with careful farming using No-till technology in similar soil and climatic zones.
